Mashed potatoes make these doughnuts moist and dense. Roll them in sugar or cinnamon sugar when they're done. 


  • 3 cups of sugar
  • 3 cups ​mashed potatoes (plain)
  • 6 large eggs
  • 1/2 cup vegetable oil
  • 1 1/2 cups milk
  • 8 cups all-purpose flour
  • 5 tablespoons baking powder
  • 2 cups vegetable or peanut oil (or enough to fill the pan with 2 to 3 inches for deep frying)

Steps to Make It

  1. Gather the ingredients.

  2. In a mixing bowl with an electric mixer, beat the sugar with the mashed potatoes until the dough is the consistency of paste. Add the eggs and beat until well blended. Add 1/2 cup of vegetable oil, milk, flour, and baking powder. More flour may be added if necessary to make a soft dough.

  3. Place dough on a lightly floured surface and roll to 1/2 inch thickness. Cut out with floured doughnut cutter.

  4. Heat about 2 to 3 inches of vegetable oil to 370 F on a deep-fat thermometer.

  5. Drop the doughnuts, 2 or 3 at a time, into the hot fat. Fry, turning once, for 3 minutes, or until golden brown. Lift the doughnuts out with a skewer or tongs and drain on paper towels.

  6. Enjoy!

Recipe Variation
